To all whom. t may concern:

Be it known that I, HEINRICH SECK, a subject of the King of Saxony, residing at Dresden, Vin the Kingdom of Saxony and German Empire, have invented new and useful Improvements in Machines for Bolting Flour and Grading Grain, of which the following is a specification.

The present invention has for its object a machine for bolting iiour and grading grain, in which the material to be bolted is projected by deliectors placed in supply and bolting passages arranged angularly to each other, and during its entire passage through the bolting-passages the material is thrown upward and downward with great force against the sieve-walls or sieves, and thereby bolted and graded even during the admission. The material to be bolted may be conveyed both in vertical and horizontal planes and upward in the longitudinal direction and laterally. The tossing effect or force with which the deilectors project the material against the sieves may be still further considerably increased by giving the supply-deiiectors a yielding and readily displaceable mounting. By this means the material is also prevented from remaining on theldeiiectors and adhering thereto in larger or smaller quantities.y

In addition to this 'obstruction or blocking of the sieves by the material projected with great force against them is prevented, owing to the fact that the sieves are given a constant shaking movement, which detaches the material and causes it to fall.

A constructional form of this machine is represented in the accompanying drawings, in which- Figure 1 is a partial vertical section through the machine. f Fig. 2 represents a part of the machine in horizontal section on Fig. 3 shows a constructional form of the bolting-machine with bolting-reservoir mounted or suspended to move in a horizontal plane, partly in plan and partly in section. Fig. 4. represents a section on the line C C of Fig. 3. Figs. 5 to 13 represent details of the arrangement, formation, and method of securing the deflectors arranged in the bolting-passages. Fig. 14 illustrates a constructional form in which the siftingreservoir is suspended from cables.

.the bolting-reservoir on cables. Figs. 17 to 19 illustrate knockers provided in or on the bolting-passages in the form of a sphere, a sliding member, and a hammer.

The machine consists of a reservoir b, suspended from or on spiralsprings a., this reservoir being given a rocking movement by means of a lcrank-shaft c, eccentric, or the like and being provided with a number, corresponding to its size, of separate but simultaneouslyacting bolting devices. In the machine of this constructional form it is assumed that various bolting devices are comprised. The bolting devices are formed of separate chambers or supply-passages d and bolting-passages e, connected one with the other by passages f g, the supply and bolting passages being arranged at an angle to each other, the passages d being horizontal and the passage e being vertical. The bolting-passages e are provided in the known manner with sieves or sieve-walls h. The passages and e, which are provided with inlets i and outlets lc in accordance with requirements, are furnished with delectors Z and m, mounted at an angle to the walls of the passages. The material to be bolted-such as reduced corn, bruised grain, groats, or the like-is introduced into the passages d through the inlets i. and then into the passages e and the bolted or sorted material-Hour, groats, and the like-is withdrawn through the outlets. The deflectors Z and m may be given any appropriate form and arranged at any suitable angle of inclination in the passages d and e. Again, the deflectors may be arranged in a number of successive rows', Figs. l, 6, and 8, and pivotally or swingingly mounted, Figs. 11,12,and 13.

As shown in Figs. 1 and 2 of the accompanying drawings, the deflectors Z, arranged 1n the-supply-passages d, are segmental and arranged at an angle to the walls or to the longitudinal axis of the passages at certain intervals from each other. Owing to the segmental Jform of the deilectors Z and their arrangement at an angle in the passages d it is possible to effect a uniform distribution of the material introduced throughout the entire length of the supplvpassages and a bolting of the material even during its introduction, and owing to the various alternating movements of the reservoir, and consequently of the chambers or passages d and e, the material is thrown in the direction indicated by the arrows in Figs. 1 and 2 in vertical and horizontal planes by one deflector in front of the( which the material is thrown remain at a certain distance from the walls or sieves of the bolting-passages e. For the conveyance of the material in the downward direction the supply-deiiectors should referably besepaated from the bolting-sur aces by a larger interval, so that the material may fall down freely. If the deflectors are turned nearer to the bolting-surfaces, they effect the feed upward. By this means the important advantage is attained that it is possible for the material to move entirely freely between the deflectors or around the same, so that the force of projection of the material is not imaired, and consequently it is repeatedly proljected with great force against the sievewalls and bolted in an exceedingly intense manner. The material entering the boltingpassages e, and therefore coming upon the deiectors m, owing to the oscillating movement of the reservoir 1),.is constantly projected in an intermittent or ste -by-step manner, say in the direction indicated by the arrows in Fig.` 1, so that it is repeatedly thrown against the sieve-walls or sieves h. In this manner the material is conveyed through all the chambers or passages of the reservoir b, gradually descending and ascending, and in this manner is bolted. The bolted material may be removed or conveyed from the several discharge-passages.

In order to increase the projecting power of the deflectors rm, in the case of soft or light bolting material, as shown in Figs. 11 to 13,

they may be hinged or pivoted in the bolt-` ing-passages. The rotatable mounting of the deilectors m may be carried out by hinging one end of the deflectors in the bolting-passages and jointing their other end to a resiliently or yieldingly mounted belt, rod, or the like o. Owing to the rocking movement of the container l), and consequently of the chambers or bolting-passages, the deilectors are likewise caused to rock, so that the material which has reached them is projected against the sieve-walls. The belts, bars, or the like o, with which one end of the deflectors is connected, merely serve to render the movement of the deiiectors fm as uniform as ossible and to limit their return into their initial position. The same effect could, however, be obtained by arranging stops in the chambers or passages for limiting the rocking i of the deflectors.

In the constructional form illustrated in 5 Fig. 13 the sieve-like walls of the passages are resiliently or yieldingly mounted. In this case the walls of the separate passages are connected one with the other by ropes, cords, or the like p, Now when the movable deflectors m return from their outwardly-swun position into their initial position one of t em (the lowermost, for example) or a number of them simultaneously strike against the cables or the like p, connecting the walls of` the sieves, by which means the sieve-walls are shaken and temporarily assume the position indicated in broken lines. Owing to this shaking of thek sieve-walls, material adhering thereto or stopping the meshes of the sieve is detached and thrown off, so that the bolting-surfaces always remain free and clean. The sievewalls or walls of the passages may, however, as shown in Figs. 1, 17, 18, and 19, be acted upon or caused to shake by means of parts mounted so as to be freely displaceable or guided or rocking in any appropriate manner-for example, by means of elastic balls, sliding members, hammers, or the like gwhich serve to loosen and throw off any material adhering to the walls and remaining in the meshes'of the sieves. The balls, which are preferably com osed of elastic material, are mounted for t 's purpose on bars arranged in the manner of a grating, and during the movement of the container b run against the walls and sieves of the passagesl e and impart to them a short shaking movement. As shown in Figs. 18 and 19, however, displaceably-mounted sliding members oi' oscillating suspended hammers might be used in place of the balls. v

In order to guide the containers b Well and uniformly during the rocking movement, as already stated, they may be suspendedI in such a manner as to be readily displaceable on spiral springs or on elastic cables, cords, rods, or the like o, in combination with such springs. As shown in Figs. 14, 15, `and 16, one or more cables, ropes, or elastic bars v are provided, on which the container b is displaceably suspended by means of bearings s. In order that the cables or the like Q; may be adjusted or tensioned as desired, they are fixed in ball-bearings u, capable of adjustment by means of screws t. Now if the container is rocked by means of the crank-shaft c, an eccentric, or the like the said container, which is carried in the manner already described on the cables, ropes, elastic bars, or the like fv, is able to adapt itself very readily to each movement. It will of course be understood that the elastic displaceability of the container or containers b might be considerably increased by simultaneously providing springs. The cables or the like serving for the suspension of the container or containers may be endless or undulatory.

The operation of the machine is briefly as follows: i The material -to be, bolted or grain IOO from falling down too speedily in the passage l e. In the bolting-passages e the material is gradually moved forward by the delectorsl m step by step in the direction indicated by the arrows, caused to circulate around the deflectors, being thrown and rubbing against the sieves or sieve-walls 7i, and thereby bolted. The bolting takes place owing to the fact that the material to be bolted which is thrown against the sieve or sieve-walls h is divided into a number of parts, the finest of which fall through the sieves or sieve-walls into an adjacent chamber e, while the coarser parts of the material are carried intermittently or step by step through the bolting passage or passages e, Athrown repeatedly against the sieves or sieve-walls, and again bolted in the manner already described. Descending and ascending in this manner and moving in a longitudinal and lateral direction the material traverses the several bolting-passages d, e, and g, and may be removed at the places or discharge passagesor outlets provided for this purpose in the different grades corresponding to the several passages.

I/Vhat I claim Vas my invention, and desire to secure by Letters Patent, is-
